NSF Minority Postdoctoral Research Fellowship for FY 2000

这项行动资助了2000年的NSF少数民族博士后研究奖学金。该研究和培训计划是在感觉系统领域，标题是“生境光和视觉信号设计的演变”。根据感觉驱动假说(SDH)的描述，动物体内的信号多样性可以用基于最佳传输和检测效率的特定信号和感觉系统的选择压力来解释。SDH可能在种群的遗传隔离和物种形成方面发挥重要作用。这项研究考察了在两种不同的栖息地类型中发现的六种异地(即发生在不同地点)的冠突蜥蜴种群。研究了环境光、视觉系统响应和信号设计。这项研究对感觉驱动在信号多样性的产生中的作用及其在新物种形成中的潜在作用提供了更好的理解。

This action funds an NSF Minority Postdoctoral Research Fellowship for 2000.The research and training plan is in the area of Sensory Systems and is entitled "Habitat Light and the Evolution of Visual-Signal Design". Signal diversity in animals may be explained by selection pressures for particular signals and sensory systems based on optimal transmission and detection efficiency, as described by the sensory drive hypothesis (SDH). The SDH may play an important role in genetic isolation of populations and, in turn, speciation. This research examines six allopatric (i.e. occurring in different locations) populations of the lizard Anolis cristatellus found in two distinct habitat types. Habitat light, visual-system response, and signal design are examined. This study provides a greater understanding of the role of sensory drive in the generation of signal diversity and its potential role in the formation of new species.
